To all whom it may concern: 1 ter are discharged with the heated Waterinto Be it known that we, JACOB F. WAGNER and the cooling apparatus andthen subjected to ARTHUR FREESTON, citizens of the United the filteringmedia for their removal. The States, residing at Philadelphia,(Germanlifting force of the current of water will hold 5 town,) in thecounty of Philadelphia and State theseimpurities at the top of thewater, which of Pennsylvania, have invented certain new here forms ascum distributed over the surand useful Improvements in Apparatus'forface of the water, and the scum thus formed the Manufacture of Ice, ofwhich the followwill readily permit of the passage of the air ing is aspecification. and gas bubbles from the water, but will pre- [0 Ourinvention has relation to apparatus in vent the outside atmosphere incontacting which water is treated prior to its discharge with the waterin the apparatus to reabsorb into a freezing tank, can, or otherappliance air and gases and also maintain the apparafor producing ice inapure state free from tus free from sediment or any settling in theair-needles or, internal honeyc'ombed condi bottom thereof.

Z) is a water-supply main located above a cooling-tank B.

b is a union perforated pipe connection, through the perforations ofwhich connection the water from a suitable source of supply, passingthrough the pipes b and I), by falling cools off the water in passagethrough the coils a". From the coils a the water thus cooled and freedof air and noxious gases is conducted through an appliance 0, containingfiltering media, wherein all impurities are removed. The water is thenconveyed by pipe connections 0 into a reservoir D, supplying in purifiedcondition the water to the ice-forming tanks E through the pipeconnection 0?, provided with a stop-cock d, and hose extension (1conducting the water to the bottom of the tank E, which by rising in thesame will not agitate the water. These tanks E are generally arranged inseries and provided with oblong cells 0, of the usual construction.

6 is a pipe connection provided with vertical branches a dependingtherefrom and terminating in a longitudinal perforated extension 6located near the bottom on the interior of each cell, through whichperforations the brine or other refrigerating media is permitted to risein the cells and exert its influence, by the chilling and freezing ofthe walls of the cell, to cause from both sides the freezing,progressively, of the water into oblong plates or blocks of ice toward avertical median plane of the body of water in each tank E, maintained ina substantially quiescent state, freed of impurities, air, and noxiousgases. The ice is thus formed without the body internally beinghoneycombed or of the formation of air-needles to become receptacles fordirt or other extraneous matterin the handling of the same, which ifthey existed therein would depreciate the value and usefulness, as wellas quality, of the ice.

5 is an exit-pipe for the brine or ammonia from each cell of the tank E.

The water in the cells of the tank E, as hereinbefore mentioned, isallowed to remain owing to its suitability and temperature for quicklyreducing in an efiective manner a fresh supply of purified water to thetanks to replace the removed plates or blocks of ice, and not, ashitherto, is it discharged into a sewer. This has been a desideratum inthe past and an expense which it has been highly desirable toovercome-that is, the discharge of the tempered water containingimpurities liberated into the same in the formation of the ice-butpractice has demonstrated that it was essential for the sale of the icemade to rid each tank after the plates or blocks of ice were formed ofthe contaminated lower' temperatured water, and also to cleanse thetanks before supplying with fresh filtered water for another freezingoperation, yet each time with the loss of a large quantity in whichenergy has been expended in tempering, and which if available could beused to expedite freezing of a fresh supply of Water to the tank, owingto the lower temperature of such water to hasten freezing of the body ofwater in the tank into ice.

By our invention, as hereinbefore described, we accomplish the above ina most practical manner without the ice being honeycombed and withoutair needles or gases therein. Furthermore, the ice produced is not sosusceptible to melting and can be safely made in one season and usedduring a subsequent season.

Having thus described the nature and objects of our invention, what weclaim as new, and desire to secure by Letters Patent, is

1. An apparatus for manufacturing ice, comprising a tank, means adaptedto distribute the water in a certain portion of said tank, means forconducting a heating media through the water in said tank in a directionopposite to the distribution and movement in volume of the water in saidtank, means for permitting of the discharge of the water in its hottestcondition in volume in said tank from the same, said tank connected witha cooling coiled tank by means of a pipe connection from said coils insaid tank and having a perforated water-discharge over said coils, afiltering appliance connected with said cooling coil-tank and through areservoir with an ice-forming tank having a cell on each side forcontaining brine or ammonia and an exit from said cell, substantially asand for the purposes described.

2. An apparatus for manufacturing ice, comprising an open tank having awater-outlet at its upper end, a series of steam-coils having an inletarranged near the Water-outlet of said tank, a steam-outlet near thebase thereof, a water-inlet pipe having branches traversing the tank andterminating at the bottom thereof, said tank connected with acooling-tank by pipe connections formed into coils in said tank andhaving a water-discharge, a filtering appliance connected with saidcooling-tank and with ice-forming tanks having cells for containingbrine or ammonia for congealing the treated fluid within said tanks andan exit from said cells, substantially as and for the purposesdescribed.

In testimony whereof we have hereunto set our signatures in the presenceof two subscribing witnesses.
